Horse Water Requirements

May 23, 2011

Dr. Tom Lenz, past president of the American Association of Equine Practitioners, clarifies how much water the average horse needs on a daily basis.


How much water does a horse in a stable require per day?


The average 1,100-pound horse will drink 10-12 gallons of water a day. That will decrease in cold weather and may go up to 15-20 gallons in very hot weather or during extreme exercise in hot weather.
